To align the FM part of the set you need a generator that goes up to more than 100MHz. If the front end is OK then you only need up to 10.7MHz for the IF.
May we have a photo of the generator's output socket please? There are some unusual conenctors that have been used. If it's a piece of kit that works for its living (as against a restoration of the kit) then I'd fit a more common connector such as BNC. At the bodgery end of things I've soldered BNC sockets to odd connectors before now.
But first and foremost, please don't mess with the alignment until all the voltages are right and you are sure there are no faulty components. Unless Mr Twiddler has been in the set before you the alignment is likely to be reasonably OK.
